Abstract

Des procédés et des systèmes permettant de détecter une position dun objet dans un corps consistent à positionner une sonde dans le corps, à prendre des mesures de mappage des courants électriques passant entre au moins une première électrode sur la sonde et une pluralité de deuxièmes électrodes sur une surface du corps, à étalonner les mesures de manière à compenser une ou plusieurs caractéristiques non idéales des mesures, notamment les effets du couplage électrique dépendant du système à un ou plusieurs dispositifs autres que la première et les deuxièmes électrodes, et à calculer la position de la sonde dans le corps au moyen des mesures étalonnées.
